You could try to poor a little oil down into too the cylinders to see if it bumps the compression up.

tried that already.. but thanks for the feedback neways.. there is a little air coming out the intake manfold when i turn it over.. i just discovered this. But the timing marks are aligned properly. hmmm... Any ideas? :

Im gonna say it HAS to be your valves man, thats crazy low compression

i consider that an option, but this problem has gotten me to think very logical and organized because it has been so frustrating. So this is my thinking of that idea. And there is a chance you are right, but this is why im not so sure. I am not trying to be a dick at all.. because i am soo0o glad people have responded to my call for help. But this is some thinking on the your thought.

1.) the valves not sealing right, or sealing incorrectly is very unlikely when the valves were functioning properly prior to the rebuild..

2.) compression being almost eliminated in all 4 cylinders means that most, or all the valves would just have to coincidencially have failed at exactly the same time. Also very unlikely

3.) The air being felt out the intake manifold is VERY apparent.. not just a slight wind. So this means that the intake valves ARE very likely to be opening during some of the compression stroke. it would take very leaky valves to yeild that much air.

So i have come to a 75% conclusion that the timing must be off, and the intake cam is letting some of the air out during the compression stroke, but the timing marks DO ALIGN! because the crank pully is twice the diameter of the cam pully, every other rotation of the crank pully hitting top dead center or 0 degrees, the cam pully is aligned with the proper timing mark. the timing belt is in very good conditing, so that eliminates the timing belt being an issue. The cam pully only fits on the intake camshaft 1 way because of the "notch and hole" design. So how the hell could the intake cam be off?! or is it?---------sigh....... back to base 1. Any good ideas would ------- make my day.. thanks.

Did you double check the valve lash? Seems too me you just think its the timming belt.

penguininatux

valve lash clearence is fine.

did u make sure to overlap the gaps in the rings caus3e if u lined them up in a stright line the air will just leek by to the oil pan and u will have horibble numbers across the board

id pull the pan and the crank and check the rings

if not make sure that your head gasket is not upside down causeing air to leak by

just a thought

good luck man

penguininatux

ahh both good thoughts.. but yeah.. i staggered the rings... and the head gasket is in right.. i mean now i've narrowed the problem down to intake cam.... something has to be wrong with a components affecting the intake cam. There is air coming out of the intake manifold when i turn the engine over. I just dont know how the valve timing could be off.

turbozcteg

check the dash mark on the cam to the gear

u could have lost the little wedge thingy and it could have spun out a little causeing it to open the valves on the exhaust stroke

jinxy

are you double sure your timing is right. :P When you set the timing did you make sure your rotor was pointing at #1?
